A mass of 50.000.000.000 is still just chump change when you compare it with the number of stars in the visible Universe. 10-22 stars or 100,000,000,000 times 100,000,000,000. If our Universe is a member of a “multiverse” then the number of universes and stars becomes numberless. If that be the case then there are numberless copies of me and you typing away at FR. I am not sure I buy into the Multiverse model though.
Well there are an estimated 100 billion galaxies in the known universe and something with half the mass of our galaxy is almost atomic in that scale.
I don't, because I never seem to be in the right one where I hit the Powerball, and the Fred Thompson / Sarah Palin ticket wins in a landslide.
